Remember last year when it seemed as though “Bridesmaids” would herald some exciting new era in which women would have a bigger stake in the summer? Oh well. It’s back to the usual assortment of capes, cars, and codpieces — back, in other words, to action. At least, though, the vision has expanded enough to let more women in on it. “The Dark Knight” has Catwoman. “Prometheus” has Noomi Rapace and Charlize Theron. “Battleship” has, um, Rihanna.
